Smart Grid and the low voltage consumer behavior facing the dynamic energy rates in the Brazil

In the coming years, the Brazilian electric system will experience a (re)evolution, from integration with the infrastructure of information technology (IT) and communications, from which the smart metering and the application of hourly rates by posts tariffs will be one of the firsts procedures adopted in order to transform the existing network in Smart Grids and definitively change the role and the participation of the consumer in the operation of electrical system. Residential consumers can be considered the most responsible for rising the peak of load in the electric system, making the system and by consequence, the invested capital, become idle in most of the time. So, programs that encourage the application of hourly rates become important, since residential consumers do not have an alternative pricing. This Hourly White Rate will be an alternative to conventional rate, which is currently applied and will provide three different tariff energy posts during the day, which are more adherent to the actual costs of the distribution system. The application of this rate is scheduled to occur after the regulation of smart meters, which will result in an economic impact that is still unknown for the Brazilian consumer. This work proposes an initial analysis of this impact, considering the application of white rate in a sample residential and it considers the distribution of consumption per tariffs posts for various ranges of consumption for low voltage consumers.
